Question about Hitachi 53SWX10B 53" Rear Projection Television

Open Question

Hitachi 50es1k powers up then "click" and no power

The set will come on for a few seconds then I hear a click and there will be no power. I can unplug the set for several hours and it will power on like normal, but after a time or two of turning it on and off it will go back to giving me the click and no power. Is this something I can fix myself by buying a new part and installing it? Is there a relay that can be replaced or is this a sign of needing a whole new power supply?

SOURCE: Hitachi 51F500 power supply?

The fact that you're getting any action from the primary or secondary relays points to an open short in one or more circuits or a short to ground in one of the Hv load circuits and the S/D circuit is simply shutting the set off in protect mode... We see that a lot with PTV's when the convergence is fouled or the HOT or FBT is shorted or something along those lines.
I will Pando the service manual if you drop me a post to my addy specifying exactly what you need. If I remember correctly the manual for this one is actually a UWX20B with a supplemental.

Powering on Hitachi TV

If all you hear is a click and you get no display on the screen, it sounds as though you need a repairman to come out and fix the circuit board. There are several things that cause this symptom on your set but the most common are convergenge amp failure, vertical, or power supply issues. Sometimes as simple as resoldering connections. Other times major troubleshooting and part replacement are required. The repair cost is usually between 175.00 and 375.00 hope you have a trustworthy and knowledgable repair person, good luck, Russmann.

Hitachi 60" picture flashes on and off.

I've had the same issue although I don't unplug everything. I turn it off and then unplug it from the wall for 10 seconds then plug it back in. Seems ok after that. Has happened 4 or 5 times over the 10 years I've owned it.

Power won't stay on

What does the light blink? Also look on the printed circuit boards right below the picture tubes and see if there is any fluid leaking on them. These are the first things we need to know.

Flashing Power Light

Located in the power supply section of the unit. There is a pico fuse (soldered in fuse) that opens up and there is no high voltage. The second click that you hear when the set is turned on. This can be diagnosed With set unplugged, with an ohm meter with a simple continuity test. I think the pico fuse is 4 amps , I am not absolutely sure. I have seen this problem in that unit previously. There is also a convergence problem that occurs with that set. Scrivitron.

I have the same problem with mine. i,m pretty sure that it is the built in surge protector is bad. Try unplugging the tv for 30 seconds then plug it back in and turn it on. If your surge protector has not completely gone bad this might work a few times. mine won't turn on at all anymore.
